In a statement to Reuters, Google said it had "filed our appeal of the EC's Android decision at the General Court of the EU." A company representative confirmed to CNET that Google has filed the appeal, but said it's not issuing a statement or sharing details about the appeal for the time being. 

In a July blog post titled "Android has created more choice, not less," Google CEO Sundar Pichai said the company would appeal the decision.
